Thecall manager module 110 may be downloaded from a network server or provided on a storage media (e.g., diskette, CD-ROM, or installed by the computer system manufacturer) to a subscribing customer or user to install on thecomputer system 100 to enable, disable, and further control a variety of the 3PCC services (e.g., providing call handling options, such as routing an incoming call to voice mail, transferring an incoming call to a particular exchange, call-waiting, setting up conference call, placing a call on hold, etc.). - The
computer system 100 also has one or morecentral processors 220 executing anoperating system 222. Theoperating system 222, as is well known, has a set of instructions that control the internal functions of thecomputer system 100. A system bus orlocal interface 232 communicates signals, such as data signals, control signals, and address signals, between thecentral processor 220 and system components. The computer system includes one or more input and/or output (I/O) devices 246 (or peripherals) that are communicatively coupled via thelocal interface 232. - In one embodiment, an interface to the
call manager client 155 may be embedded in a web page that is loaded in aweb browser 160. Upon start up of thecall manager client 155, theclient 150 connects to theinstant messaging server 120 and performs a login to theserver 120. Theclient 150 then establishes presence with thecall manager module 110 and passes credentials to authenticate theclient 150 and associated user(s). Theinstant messaging server 120 establishes an instant messaging session on behalf of theclient 150 and sets up a connection with thecall manager module 110, which communicates with anetwork switch 140. - In one embodiment, the
instant messaging server 120 utilizes a publish-subscribe (pubsub) model to relay presence information, where users or applications subscribe to receive notifications of presence information and presence information is updated. Subscription requests may have to be approved or be pre-approved by the user or application providing the presence information to theinstant messaging server 120. Only approved subscribers may then retrieve updated presence information. - The
call manager client 155, in one example, is shown residing in a memory subsystem 312, as shown inFIG. 3 . Thecall manager client 155, however, could also reside in flash memory or a peripheral storage device. Thecomputer system 150 also has one or morecentral processors 320 executing an operating system 322. The operating system 322, as is well known, has a set of instructions that control the internal functions of thecomputer system 150. A system bus orlocal interface 332 communicates signals, such as data signals, control signals, and address signals, between thecentral processor 320 and system components. The computer system includes one or more input and/or output (I/O) devices 346 (or peripherals) that are communicatively coupled via thelocal interface 332. - The system memory device 312 may also contain an application program, such as a
web browser 160, as previously discussed. Theweb browser 160 cooperates with the operating system 322 and with adisplay unit 346 to provide a graphical user interface (GUI) for thecall manager client 155, as previously discussed. As is apparent to those skilled in the art, thecall manager client 155 is selected and arranged to provide branch exchange phone capabilities (e.g., transfer, hold, block, send to voice mail, etc.) while using consumer grade hardware and setting up an intelligent instant messaging client as a transport mechanism for PBX services. Accordingly, an instant message protocol may be used as a transport for performing Third Party Call Control (3PCC) of telephone services. - In one embodiment, the
call manager client 155 allows a user to manage handling of incoming calls, such as (1) sending an incoming call to voice mail; (2) placing a call on hold, which may be accompanied by music instead of dead air; (3) setting up a conference call by adding an external party to the call; (4) forwarding or transferring the incoming call to another telephone number; etc. - Typically, a subscribing customer (i.e., a customer of a 3PCC service) or a user at the customer's premises has access to the
computer system 150 and/or thetelephone 160. For example, if a user wishes to call a particular telephone number, the user may usetelephone 160 to dial the telephone number and establish a voice connection. If, however, the user wishes to send, receive, or access voice, video, and/or data (e.g., read and respond to e-mail, order products, view video-clips, listen to music, engage in an interactive gaming session, etc.), thecomputer system 150 may be used to access the Internet. - Whether the user is attempting to make a voice connection or a data connection, each telephone number dialed from the customer's premises is sent to the
network switch 140.Network switch 140 analyzes the destination telephone number and determines routing of the outgoing call. Depending on the dialed telephone number, thenetwork switch 140 may route the outgoing call immediately over a PSTN to attempt a connection or thenetwork switch 140 may route the call over a packet network to attempt a connection with an IP-based telephone. Further, thenetwork switch 140 may communicate with a service control point (SCP) or similar database for further call processing and routing information. - The
network switch 140 may therefore include a packet-based “softswitch” that uses software control to provide voice, video, and/or data services by dynamically changing its connection data rates and protocols types. If thenetwork switch 140 should include a softswitch, an application server interfaces with the softswitch via a packet protocol, such as Session Initiation Protocol (SIP). For a PSTN type of switch,network switch 140 includes Advanced Intelligent Network (AIN) componentry controlling many features of the network. The signaling between thecomputer system 150, theswitch 140, the PSTN including AIN componentry and/or application server interfaces are well understood in by those of ordinary skill the art and will not be further described. - According to exemplary embodiments, the
call manager module 110 communicates using transmission control protocol and Internet protocol (TCP/IP). Thecall manager module 110 may store a database of user profiles including information used to communicate with a respective user over an instant messaging session, such as instant messaging addresses. The user interacts with thecall manager client 155 to access and log into theinstant messaging server 120 and to establish an instant messaging session. The callmanager module stub 115 of theinstant messaging server 120 has access to the user's current presence status and instant messaging address since the user authorizes the Call Manager service to access this information or has provided such information to the respective components. - A telecommunications system in accordance with
FIG. 1 may detect an incoming call to a computer or network station, such as acomputer system 150. The incoming call is placed by a caller to a telephone number assigned to thecomputer system 150. The incoming call to the called telephone number is associated with thecomputer system 150. Because, however, a data connection is already established between thecomputer system 150 and theinstant messaging server 120, in an embodiment, theswitch 140 requests thecall manager module 110 to route an incoming call notification to the network station over the instant messaging session between theinstant messaging server 120 and thecomputer system 150. This incoming call notification alerts the called party that an incoming call has been received and prompts a user of thecomputer system 150 to choose an option for disposing of the call. By responding to the notification, thecomputer system 150 may direct the telephone call to another exchange, such asVoIP phone 160. - In
FIG. 1 ,computer system 150 has been described as being used to make call dispositions. However, any communications device having instant messaging capabilities may be used in such a manner, including, for example, a personal digital assistant (PDA), an interactive television, a broadband telephone with instant messaging capabilities, etc. -
FIG. 4 illustrates a flowchart showing an overview of a process for call management according to an embodiment of the present disclosure. A customer or user connects to a data network and establishes an instant messaging session (block 410). A telecommunications network detects (block 420) an incoming communications signal to a called telephone number associated with the user. The telecommunications network queries (block 425) theinstant messaging server 120 to determine if the user is presently active on an instant messaging session. If the user is presently active on an instant messaging session, the telecommunications network sends (block 430) a notification message to the user over the instant messaging session. The notification message is received by thecomputer system 150 of the user. Thecomputer system 150 displays (block 440) information regarding the incoming call (e.g., caller-ID information) to the user and prompts (block 450) the user to choose an option for disposing of the call. The user replies with an instant messaging containing selection of the desired option, which is communicated (block 460) to the telecommunications network over the instant messaging session. The telecommunication network receives the reply message and disposes (block 470) of the incoming call in accordance with the selection made by the user. -
FIG. 5 is a flow diagram for one embodiment of the system ofFIG. 1 . In the figure, thecall manager client 155 provides (1) presence information to theinstant messaging server 120 on the availability of the user. Theinstant messaging server 120 passes (2) the presence information to thecall manager module 110. Thecall manager client 155 also logs (3) into theinstant messaging server 120, which causes theinstant messaging server 120 to inform (4) thecall manager module 110 that the user is active in an instant messaging session. In one embodiment, thecall manager module 110 proceeds to establish (5) a connection between thecall manager client 155 and thenetwork switch 140. Acknowledgment of the connection is passed (6) from thenetwork switch 140 to thecall manager module 110. Thecall manager module 110 passes or relays (7) the acknowledgement to theinstant messaging server 120. Theinstant messaging server 120 passes (8) the acknowledgement to thecall manager client 155. -
FIG. 6 is a flow diagram for one embodiment of the system ofFIG. 1 . In the figure, a thirdparty network device 180, such as a VoIP telephone, sends (1) an invite message to thenetwork switch 140 attempting to make a connection with a network station, such ascomputer system 150 hosting thecall manager client 155. Thenetwork switch 140 updates thecall manager module 110 of the new call request. Thecall manager module 110 uses (3) theinstant messaging server 120 to send (4) an instant message to thecall manager client 155 alerting a user of theClient 155 of the new call and providing the user options for handling the call. The options are displayed to the user at thecomputer system 150. - In this example, the user selects the option of sending the call to voice mail. Accordingly, an instant message is sent (5) from the
call manager client 155 to thecall manager module 110 via (6) theinstant messaging server 120. The instant message contains the user's selection of the desired option for handling or disposing of the call. Thecall manager module 110 receives the instant message and then instructs (7) thenetwork switch 140 on the desired action which is to send the call to voice mail. Thenetwork switch 140 in response transfers (8) the call to voice mail in accordance with the end user's instructions. -
FIG. 7 is a flow diagram for one embodiment of the system ofFIG. 1 . In the figure, a user at thecall manager client 155 “clicks” on a telephone number as part of a graphical interface, whether in an address book interface or on a web page, intending to have thecall manager client 155 cause the clicked telephone number to be called over VoIP communications. In response to clicking the telephone number, thecall manager client 155 sends (1) an instant message to theinstant messaging server 120 identifying the clicked telephone number. The instant message is relayed (2) to thecall manager module 110 from theinstant messaging server 120. Thecall manager module 110 receives the message and then instructs (3) thenetwork switch 140 to attempt a telephone call between a network terminal, such as atelephone 160, of the user and athird party phone 180 associated with the clicked telephone number. Accordingly, thecall manager module 110 establishes a session on behalf of thecall manager client 155 with thenetwork switch 140 and relays the desired call disposition. - Accordingly, the
network switch 140 sends (4) an invite message to the user'stelephone 160. An invite message is also sent (5) to thethird party telephone 180 associated with the clicked telephone number and additional signaling may then be performed to establish the call. - Referring now to
FIG. 8 , a flow chart diagram of one embodiment, among others, of a method of controlling disposition of a call is shown. In the method, an incoming call to a network station (e.g., a telephone, a computer, etc.) is detected (810) by anetwork switch 140. In response to the detection of the incoming call, an active instant messaging session for the network station is checked (820) by communications between thenetwork switch 140,call manager module 110, andinstant messaging server 140. If the active instant messaging session exists, an instant message to the network station is then sent (830) with call disposition choices with regard to the incoming call from thecall manager module 110 via theinstant messaging server 140. In one embodiment, a carrier network device, such as a VoIP feature server and/or softswitch may implement and perform the aforementioned operations. For example, the carrier networking device may facilitate an exchange service to the network station. The method may also include additional operations such as receiving a reply from the network station with a selected choice for disposing of the incoming call and disposing of the call in accordance with the selected choice. At the network station, contents of an instant message received from thecall manager module 110 may be displayed with a web browser application, in some embodiments. Accordingly, an end user would not have to invest in expensive hardware or software to receive exchange services from a carrier network. Further, the instant messaging infrastructure is readily available to be used by any carrier network wanting to provide exchange services in accordance with the present disclosure. - Embodiments of the present disclosure provide an interface to the network switch 140 (e.g., Broadsoft switch) for the
call manager client 155 via an Instant Messaging session (e.g., using extensible messaging and presence protocol (XMPP) via Jabber Instant Messaging and Presence technology). In one embodiment, the call manager client is a Flash application on a computing device. - Several exemplary implementations of various embodiments of the present disclosure are described herein; however, various modifications and alternate embodiments will occur to those of ordinary skill in the art. For example, the
call manager client 155 and/orcall manager module 110 discussed above may be physically embodied on or in a computer-readable medium, such as a CD-ROM, DVD, tape, cassette, floppy disk, memory card, and large-capacity disk (such as IOMEGA, ZIP, JAZZ, and other large-capacity memory products). This computer-readable medium, or media, could be distributed to end-customers, licensees, and assignees. These types of computer-readable media, and other types not mention here but considered within the scope of this disclosure (such as an Internet file that could be downloaded to thecomputer system 110, 150), allow thecall manager client 155 and/orcall manager module 110 to be easily disseminated. Accordingly, the present disclosure is intended to include those other variations, modifications, and alternate embodiments that adhere to the spirit and scope of this disclosure. - Certain embodiments of the present disclosure can be implemented in hardware, software, firmware, or a combination thereof.
